What is ECI?

The Estimated Chargeable Income (ECI) is a projection of a company's taxable profits for a specific Year of Assessment (YA). This figure is derived after deducting tax-allowable expenses from the anticipated taxable income for the fiscal year. The primary income, which includes revenue from core business activities like sales of goods or services, is considered for ECI calculation. Other income sources, such as gains from property sales, dividends, or rental income, are typically included as ECI should be as comprehensive as possible..

ECI is characterized by IRAS as a projection of a company's taxable revenue for a designated valuation year, tailored to each business. The ECI declaration encompasses the company's revenue, excluding specific elements like profits from the sale of assets such as property or machinery. For instance, if a company transitions into an investment holding entity, its primary revenue source becomes investment returns.

Who Needs to File ECI?

All companies in Singapore are obligated to file ECI, with a few exceptions:

  • Companies with an annual revenue of SGD 5 million or less and a nil ECI for the Year of Assessment (YA).
  • Specific entities like foreign universities, foreign ship owners, designated unit trusts, and certain approved CPF unit trusts.

Steps to File ECI:

Authorization: Ensure that you or a representative is authorized as an “Approver” for Corporate Tax (Filing and Applications) in CorpPass. Only the "Approver" can file the ECI with IRAS.

Documentation: Prepare essential documents, including your Singpass, company’s Unique Entity Number (UEN), CorpPass login details, and necessary accounting records.

ECI Submission: Log into the IRAS portal and file your company’s ECI. The government provides digital guides to assist in the process.

ECI Filing Timeline

Companies should aim to apply for ECI within three months post their financial year's end. Extensions might be available in certain scenarios, but it's advisable to adhere to the standard timeline.

Payment After ECI Filing

Upon receiving the Notice of Assessment from IRAS, companies must pay the assessed tax amount. Payment methods include the GIRO system and electronic payment options like Internet Banking, Phone Banking, and NETS.

Benefits of Filing ECI

Implementing ECI offers several benefits, particularly for SMEs. One of the most notable advantages is the Corporate Income Tax (CIT) refund. Additionally, early ECI submissions can avail flexible tax payment options, allowing businesses to pay in installments.

Consequences of Late or Incorrect ECI Filing

Late or disqualified ECI filings can lead to a Notice of Assessment (NOA) Type 2. Companies can object to this assessment within two months of receiving the notice. However, the full tax amount stated in the NOA must be paid within a month of its issuance.


Understanding and complying with ECI regulations is crucial for businesses operating in Singapore. It not only ensures alignment with taxation norms but also offers financial benefits. Companies should be proactive in their approach, ensuring timely submissions and leveraging the advantages that come with it.
